[antlr-interest] Transforming Comments along with trees

[dsfsdf fdsfdsf]

hi
no i am not setting my comment to be skipped in my lexer.
After i do my parsing build up my source tree and tree walk,and 
i can see the hidden tokens.
When i try and verify the tree and do my passes no hidden tokens present.
Should i be setting my comment to a specific type in my lexer?
thanks 
ed

Does your lexer allow comments to return or do you set Token.SKIP? 
Mostly likely that is the issue.
